Nomex Electrical Insulation

DuPont nomex insulating paper/nomex-t410 insulating paper is widely used in generators, transformers, electrical equipment, electromechanical and household appliances, most of the electrical equipment
Electrical insulation, the thickness is 0.05mm, 0.08mm, 013mm, 0.18mm, 0.25mm, 0.3mm, 0.38mm, 0.51mm, 0.6mm, 0.76mm, the specific gravity is 0.7 ~ 0.2,
Due to the calendering treatment, its inherent dielectric strength, mechanical properties, flexibility and elasticity are all high, and it has fire and flame retardancy (v0 level), high voltage resistance, and high temperature electrical resistance.
Insulation performance and other characteristics. Imported DuPont nomex insulating paper/nomex-t410 can be used for almost all known sheet insulation.

1. High voltage resistance, insulation. Imported Noemi paper products that have been calendered can withstand a short-term voltage field strength of 18~40kv/mm, without further treatment with varnish and resin;
Due to the low dielectric constant of nomex products, the electric field distribution between the insulation and the cooling medium is more uniform;

2. Mechanical toughness. Imported Noemi paper after calendering has very high strength, good elasticity, tear resistance and abrasion resistance, and thinner products have flexibility;

3. High temperature resistance. Imported Noemi paper has the approval of ul material temperature grade 220°c, which means that it can maintain effective performance for more than 10 years even if it is continuously placed at 220°c;

4. Chemical Compatibility. Imported Noemi paper is basically not affected by most solvents, and is very resistant to acid and alkali corrosion. It mixes easily with all varnishes, adhesives, transformers
Fluid, lubricant and refrigerant compatible. In addition, imported Noemi paper will not be damaged by insects, fungi and molds;

5. Low temperature performance. At the boiling point of nitrogen (77k), the tensile strength of imported nomext410 and imported Nomex 993, 994 type laminates exceeds the strength value at room temperature;

6. Not sensitive to moisture. When the phase humidity of imported Noemi paper is 95%, its dielectric strength is 90% of that in a completely dry state. At the same time, many mechanical properties have actually been improved;

7. Radiation resistance. Even if the intensity of the ionizing radiation reaches 800 Mrad (8 MGy), the imported Nomi paper is basically not affected, and after 8 times of radiation of this dose, it still maintains its
Maintain its mechanical and electrical properties;
